I want to build a GPU mining rig. I want to get as many MH/s per USD as I can, hopefully 2. But the most important thing is a money efficient computer and PSU for the GPU as I only have a laptop.
I can spend 0.5 BTC max. Any ideas?
And please do not tell me "but 1 GH/S is only $5!"
This is not for scrypt so please don't move to the altcoin subforum. This is for an algo similar (and involving) to SHA-256 and gets about the same hashrates. If you're wondering it is the Skein-SHA256 algorithm.
